More about Microwave does not heat
Microwave not heating food is a commonly occurring problem. A microwave transfers heat to food items through a process called ‘Microwave Convection’. There are many reasons behind “microwave not heating” food. In order to know your microwave better, it is very important to understand these reasons.
Reasons behind microwave not heating
Diode burn: A microwave has some very important parts called diode and magnetron. The diode converts incoming A/C power to high voltage D/C. This high voltage is used to provide energy to magnetron which in return emits heat energy to cook food. So when the diode fails or burns, magnetron does not get power to emit heat energy to cook food.
Magnetron Failure: One of the most common reason of microwave not heating is magnetron failure. A magnetron uses high voltage to produce microwave frequency to cook food. If the microwave is turned on when it is empty, this cause the magnetron to burn out. A burned magnetron has to be replaced as it cannot be repaired.
Faulty door switch: Another common reason behind microwave not heating is faulty door switch. Most microwave models normally have 3 door switches. When either of the door switches go bad, microwave does not heat food. In some case, if the door switches becomes defective, microwave needs repair.
Faulty capacitor: The capacitor works with the diode to convert the A/C power to D/C voltage. If the capacitor is burned out, the entire high voltage circuit stops working. As a result the magnetron cannot be powered and microwave does not heat. A powerless magnetron cannot emit heat to cook food.
Faulty Transformer: Defective transformer stops a microwave from heating food. When the transformer burns, the process of converting A/C power to D/C does not start. As a consequence magnetron could not be powered and a powerless magnetron cannot emit heat to cook food. In such situation a microwave needs repair.
These are some common reasons behind microwave not heating problem but there can be other reasons as well. Call a professional service provide for microwave repair if it fails to heat efficiently.
What is included in microwave repair service?
The PRO visits client’s site and troubleshoots the microwave. The PRO looks for all possible reasons behind microwave heating problem. After the actual problem is identified, PRO describes the problem to the customer and suggests a possible repair or replacement. On customer consent, the PRO repairs the microwave.
